Issues And Trends In Healthcare Delivery System

5.9K
The issues and trends in healthcare delivery are constantly changing. The COVID-19 pandemic is one recent issue that wreaked havoc on healthcare systems, causing a shortage of healthcare workers, high demand for medicines and supplies, and increased medical expenditure due to a lack of insurance. Other issues include rising healthcare costs and care fragmentation.
Cost Containment
Payment for healthcare services has historically promoted adoption of costly and often unnecessary or inefficient...

Design Example: Sustainability in Concrete Building

250
As the construction industry moves towards more eco-friendly practices, concrete's adaptability and its ability to incorporate sustainable features make it a key material in the drive towards greener building solutions.
There are multiple approaches to achieve sustainability in a commercial concrete building. For instance, construct a concrete parking area under the building, utilizing pervious concrete paver blocks in open areas to facilitate rainwater collection through an underground...

Social Traps

24.4K
Social traps are negative situations where people get caught in a direction or relationship that later proves to be unpleasant, with no easy way to back out of or avoid. The concept was orignally introduced by John Platt who applied psychology to Garrett Hardin's "Tragedy of the Commons", where in New England herd owners could let their cattle graze in the common ground. This situation seems like a good idea, but an individual could have an advantage. If they owned...

Community Based Intervention

124
Community-based interventions in mental health represent a paradigm shift from institution-centered care to treatments embedded within the fabric of local communities. By prioritizing inclusion and leveraging existing societal structures, this approach fosters a supportive environment conducive to addressing mental health challenges while promoting individual dignity and agency.
Foundations of Community Mental Health Programs
Central to the success of community-based interventions is the...

Introduction to GIS01:28

Introduction to GIS

262
Geographic Information Systems (GIS) are tools for storing, analyzing, and displaying spatial data alongside related attributes. Unlike traditional information systems that address general queries, GIS incorporates spatial components, enabling users to answer "where" and "how far." For example, GIS can process housing data linked to geographic locations like zip codes, allowing insights into population density or housing distribution through thematic maps.GIS integrates technologies such as...

Ethical Standards I01:25

Ethical Standards I

1.2K
The American Nurses Association (ANA) created and implemented the first nationally accepted Code of Ethics for Nurses with Interpretive Statements. The Code of Ethics is a living document regularly updated by the ANA and establishes an ethical standard that is non-negotiable for nurses in all roles and settings.
The Code of Ethics provisions outline the nurse's duty to the patient, the healthcare team, the profession, and society. The Code's fundamental principles include advocacy,...

Area of Science:

  • Computer Science
  • Cybersecurity
  • Distributed Systems

Background:

  • Smart cities rely on Internet of Things (IoT) devices for improved services.
  • Securing IoT data sharing across organizations presents significant access control challenges.
  • Existing solutions often lack the flexibility required for large-scale, cross-organizational deployments.

Purpose of the Study:

  • To propose a novel entitlement-based blockchain-enabled access control architecture for smart cities.
  • To enable secure and flexible sharing of IoT data among diverse users and organizations.
  • To address the limitations of traditional access control models in large-scale IoT environments.

Main Methods:

  • Developed an entitlement-based access control model.
  • Designed and implemented the architecture using Ethereum blockchain.
  • Conducted qualitative evaluation of security and access control features.
  • Performed experimental validation on private Ethereum test networks.

Main Results:

  • The proposed architecture facilitates secure delegation of access rights beyond organizational trust boundaries.
  • Implementation on Ethereum blockchain demonstrated feasibility and low latency.
  • Security and access control aspects were qualitatively evaluated and found robust.
  • Experimental results indicate applicability to real-world IoT environments.

Conclusions:

  • The entitlement-based blockchain architecture offers a flexible and secure solution for IoT data access control in smart cities.
  • The model effectively addresses the challenge of sharing data across organizational boundaries.
  • The low latency and feasibility demonstrated in experiments support its real-world deployment potential.
